Description

Technical Field

[0001] The invention relates to the field of mechanical technology, and in particular to a cargo storage device. Background Art

[0002] Shelves are widely used in both logistics systems and supermarket storage systems. Items of the same or different models can be placed on the shelves, making it convenient for operators to distinguish, retrieve and temporarily store items.

[0003] Common shelf layers are fixed horizontally and can only hold items of a specific height or below, which makes the shelf utilization rate and ease of use not high. In the prior art, there are many improvements to the shelf structure so that the height of the shelf layer can be adjusted, such as improvements to the fixed plate and support plate of the shelf. However, the improved structure is complex and the operation steps are cumbersome, which is not conducive to improving ease of use. Summary of the invention

[0004] Based on this, it is necessary to provide a storage device that can adjust the height or angle of the shelf through an adjustment mechanism and a flexible structure, thereby saving manpower and material resources, simplifying the replenishment steps, and improving replenishment efficiency; a structure that can achieve two adjustment effects of shelf height and angle reduces the complexity of the structure and improves ease of use.

[0005] The technical solution is as follows:

[0009] The adjusting mechanism is connected to the two ends of the layer mechanism through the flexible structure, and the adjusting mechanism shortens or lengthens the length of the flexible structure to make the two ends of the layer mechanism translate upward or downward at the same time; or, the adjusting mechanism shortens or lengthens the length of the flexible structure to make one end of the layer mechanism rise and the other end fall, so that the layer mechanism rotates upward or downward around the axial direction.

[0010] In one embodiment, each of the layer plate mechanisms controls two ends of the layer plate mechanism respectively through two adjustment mechanisms, and each of the adjustment mechanisms controls two sides of one end of the layer plate mechanism through two flexible structures;

[0011] When the two adjusting mechanisms respectively control the two ends of the layer plate mechanism to rise or fall simultaneously through the four flexible structures connected thereto, the two ends of the layer plate mechanism are translated upward or downward simultaneously;

[0012] Alternatively, when one of the adjustment mechanisms controls one end of the layer plate mechanism to descend through the two flexible structures, and another adjustment mechanism controls the other end of the layer plate mechanism to ascend through the two flexible structures, the layer plate mechanism is caused to rotate downward around the axial direction;

[0013] Alternatively, when one of the adjustment mechanisms controls one end of the layer mechanism to rise through the two flexible structures, and another adjustment mechanism controls the other end of the layer mechanism to descend through the two flexible structures, the layer mechanism rotates upward around the axial direction.

[0014] In one embodiment, when there are multiple layer mechanisms, the storage device includes the same number of adjustment mechanisms, and each layer mechanism is connected to the corresponding adjustment mechanism through the flexible structure.

[0017] When the motor drives the screw rod to rotate, the screw rod drives the nut forward or backward, thereby driving the second fixed block connected to the nut and the first fixed block connected to the screw rod to run towards or in the opposite direction, shortening or lengthening the flexible structure connecting the first fixed block and the second fixed block respectively, thereby causing one end of the layer mechanism to rise or fall.

[0018] In one embodiment, the hoisting adjustment mechanism includes a motor and a reel; a flexible structure is connected to the top and bottom of the reel respectively. When the motor rotates, it drives the reel to rotate, shortening or lengthening the flexible structures connected above and below respectively, thereby causing one end of the layer mechanism to rise or fall.

[0019] In one embodiment, when there are multiple connecting rod adjustment mechanisms, the connecting rod adjustment mechanisms are arranged on the top plate in a stacked manner.

[0020] In one of the embodiments, the fixing mechanism further includes a top plate; when the number of the hoisting adjustment mechanisms is plural, the hoisting adjustment mechanisms are arranged on the top plate in a staggered manner, and the staggered manner includes up-down staggering and front-back staggering.

[0021] In one of the embodiments, the side panel is provided with a slide groove, the guide wheel is located in the slide groove, and the layer mechanism includes a connection with the side panel through the guide wheel in the slide groove; the layer mechanism is translated upward or downward through the guide wheel, and the layer mechanism changes the inclination angle through the wheel axle in the guide wheel.

Rotation; when the two adjustment mechanisms rise or fall at the same time, the flexible structure can be used to make the shelf mechanism move upward or downward horizontally, thereby changing the height between the two shelf mechanisms, so that the storage device can accommodate items of different heights and improve ease of use; by adjusting one adjustment mechanism to rise and the other adjustment mechanism to fall through the flexible structure, the inclination angle of the shelf mechanism is changed, and the one or more items will slide into the inside of the shelf mechanism under the action of gravity. Users only need to replenish items from the periphery, which greatly saves manpower and material resources, simplifies the replenishment steps, and improves replenishment efficiency; a structure that realizes the adjustment effect of the height and angle of the shelf mechanism reduces the complexity of the structure and improves ease of use.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0036] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0037] Reference Figure 1 , showing a schematic diagram of a storage device of the present invention, such as Figure 1 As shown, the cargo storage device includes a layer plate mechanism 1, a fixing mechanism 2, an adjustment mechanism 3 and a flexible structure 4; wherein the fixing mechanism 2 includes a side plate 21;

[0038] Furthermore, the layer plate mechanism 1 is connected to the side plate 21 via a guide wheel 22; the side plate 21 is used to fix the layer plate mechanism 1; the layer plate mechanism 1 is used to store items;

[0039] Specifically, the layer mechanism 1 is connected to the side plate 21 through a guide wheel 22; the layer mechanism 1 is translated upward or downward through the guide wheel 22, and the layer mechanism 1 changes its tilt angle through the axle in the guide wheel 22; the layer mechanism 1 is used to store items;

[0040] It should be noted that the fixing mechanism 2 may also include a top plate, a back plate, etc. The fixing mechanism 2 may be used by the user to fix the shelf mechanism 1. In addition, the fixing mechanism 2 may also play a protective role to prevent items stored on the shelf mechanism 1 from being damaged.

[0041] In addition, the fixing mechanism 2 further includes a slide groove 21, on which a guide wheel 22 is disposed. Figure 2 , showing a schematic diagram of a guide wheel 22 of the present invention, the guide wheel 22 includes a wheel body 221 and a rotating shaft 222, the wheel body 221 is located in the slide groove 21, and the rotating shaft 222 is connected to the layer mechanism 1, that is, the layer mechanism 1 includes a corresponding hole, and the rotating shaft 222 is connected to the layer mechanism 1 through the hole.

[0042] like Figure 1 As shown, the fixing mechanism 2 is a support plate, but in a preferred embodiment, the fixing mechanism 2 can be an H-shaped support column, such as the fixing mechanism 2 can be a supporting steel structure, etc., as long as it can connect the layer plate mechanism 1 to the fixing mechanism 2, this embodiment does not limit this.

[0043] Furthermore, the material of the fixing mechanism 2 can be plastic, metal, wood, etc., and this embodiment does not impose too many restrictions on this.

[0044] Specifically applied to this embodiment, the flexible structure 4 may include steel wire, steel rope, steel cable, chain, plastic rope or plant fiber rope, etc., and this embodiment does not limit this. The flexible structure 4 may include a rope body made of metal material and non-metal material that plays a connecting and traction role. In addition to steel wire, steel rope, steel cable, chain, etc., the flexible structure of metal material may also include copper-plated wire rope, iron wire rope, alloy rope, etc., and in the flexible structure of non-metal material, the above-mentioned plastic rope may include nylon rope, synthetic fiber rope, and plant fiber rope may include a rope body made of cotton, hemp, palm fiber, etc. In short, no matter what kind of material the flexible structure 4 is made of, as long as it plays a role in connecting the traction layer mechanism, it falls within the protection scope of this embodiment.

[0045] Further applied to the present embodiment, the adjusting mechanism 3 is connected to the two ends of the layer mechanism 1 through the flexible structure 4, and the adjusting mechanism 3 shortens or lengthens the length 4 of the flexible structure so that the two ends of the layer mechanism 1 move upward or downward at the same time; or, the adjusting mechanism 3 shortens or lengthens the length 4 of the flexible structure so that one end of the layer mechanism 1 rises and the other end falls, so that the layer mechanism 1 rotates upward or downward around the direction of the wheel axle.

[0046] Specifically, the adjustment mechanism 3 is connected to the outer ends of the layer mechanism 1 through the flexible structure 4. The connection position between the flexible structure 4 and the layer mechanism 1 can be the edge position where the layer mechanism 1 is connected to the fixing mechanism 2, or it can be the vertex position of the layer mechanism 1, which is convenient for force bearing. This embodiment does not impose any restrictions on this.

[0047] For the two ends of the layer plate mechanism 1, the intersection of the layer plate mechanism 1 and the above-mentioned back plate can be taken as one end, and the opposite end of the layer plate mechanism 1 can be taken as the other end; the adjustment mechanism 3 can control the rise or fall of one end of the layer plate mechanism 1 through the above-mentioned flexible structure 4. When the adjustment mechanism 3 controls one end of the layer plate mechanism 1 to rise through the above-mentioned flexible structure 4, and the other adjustment mechanism 3 controls the other end of the layer plate mechanism 1 to fall through the above-mentioned flexible structure 4, the inclination angle of the layer plate mechanism 1 can be changed. When the adjustment mechanism 3 controls the two ends of the layer plate mechanism 1 to rise or fall at the same time through the above-mentioned flexible structure 4, the relative height of the layer plate mechanism 1 can be changed. When the two adjustment mechanisms 3 rise or fall at the same time, The layer mechanism 1 can be moved upward or downward to change the height between the two layer mechanisms 1, so that the storage device can accommodate items of different heights, thereby improving ease of use; after the user places one or more items on the periphery of the layer mechanism 1, one adjustment mechanism 3 is adjusted to rise, while the other adjustment mechanism 3 is adjusted to fall, thereby changing the inclination angle of the layer mechanism 1, and the one or more items will slide into the inside of the layer mechanism 1 under the action of gravity. The user only needs to replenish items on the periphery, thereby greatly saving manpower and material resources, simplifying the replenishment steps, and improving replenishment efficiency; a structure that realizes the adjustment effect of the height and angle of the layer mechanism reduces the complexity of the structure and improves ease of use.

[0048] Reference Figure 3 and 4 , showing a schematic diagram of a storage device of the present invention, such as Figure 3 and Figure 4 As shown, each of the layer plate mechanisms 1 controls the two ends of the layer plate mechanism 1 respectively through two adjusting mechanisms 3, and each of the adjusting mechanisms 3 controls the two sides of one end of the layer plate mechanism 1 through two flexible structures 4;

[0049] That is, each layer plate mechanism 1 can be controlled at both ends by two adjustment mechanisms 3. Preferably, one adjustment mechanism 3 can control the two vertex angles of one end through the flexible structure 4 to facilitate movement.

[0050] Specifically, when the two adjustment mechanisms 3 respectively control the two ends of the layer mechanism 1 to rise or fall simultaneously through the four flexible structures 4 connected thereto, the two ends of the layer mechanism 1 are simultaneously translated upward or downward, thereby changing the relative height of the layer mechanism 1;

[0051] Further applied to this embodiment, when a certain adjusting mechanism 3 controls one end of the layer plate mechanism 1 to rise through the two flexible structures 4, and another adjusting mechanism 3 controls the other end of the layer plate mechanism 1 to descend through the two flexible structures 4, the layer plate mechanism 1 is caused to rotate upward around the axial direction;

[0052] Alternatively, when one of the adjustment mechanisms 3 controls one end of the layer mechanism 1 to descend through the two flexible structures 4, and another of the adjustment mechanisms 3 controls the other end of the layer mechanism 1 to ascend through the two flexible structures 4, the layer mechanism 1 is caused to rotate downward around the axial direction;

[0053] The technical effect of adjusting the angle of the layer plate mechanism 1 can be achieved by controlling one end to rise and the other end to fall, thereby improving the convenience of users replenishing goods; one structure can achieve both the effects of adjusting height and angle, with a simple structure and high operating effect.

[0054] Reference Figure 5 and Figure 6 , showing a partial enlarged view of a storage device of the present invention, such as Figure 5 and Figure 6 As shown, when there are multiple layer mechanisms 1 , the storage device includes the same number of adjustment mechanisms 3 , and each layer mechanism 1 is connected to the corresponding adjustment mechanism 3 via the flexible structure 4 .

[0055] The number of the adjusting mechanisms 3 will increase with the number of the layer mechanisms 1. For example, the layer mechanisms 1 can be 7, and the number of the adjusting mechanisms 3 is 14, because one layer mechanism 1 needs to be controlled by two adjusting mechanisms 3, and each adjusting mechanism 3 needs to be connected to two flexible structures 4, such as Figure 5 and Figure 6 The flexible structures 41 , 42 , 43 , 44 , 45 , 46 , and 47 respectively control a top corner or an outer edge of the seven layer plate mechanisms 1 .

[0056] It should be noted that this embodiment does not impose too many restrictions on the number of layer mechanisms 1, and the number can be 9, 10, etc. Similarly, there is no excessive restriction on the number of adjustment mechanisms 3.

[0057] Reference Figure 7 , showing a schematic diagram of a connecting rod adjustment mechanism 31 of the present invention, such as Figure 7 As shown, the adjustment mechanism 3 may include a connecting rod adjustment mechanism 31 .

[0058] Specifically, the connecting rod adjustment mechanism 31 includes a motor 315 and a connecting rod structure; the connecting rod structure includes a nut 317, a first fixing block 314, a second fixing block 313 and a connecting rod connecting the first fixing block 314 and the second fixing block 313, the nut 317 is connected to the second fixing block 313, the motor 315 is arranged in the first fixing block 314, the first fixing block 314 and the second fixing block 313 are respectively connected to the screw rod 316, and the first fixing block 314 and the second fixing block 313 are respectively connected to the slide groove 6 through the guide wheel 22, and the first fixing block 314 and the second fixing block 313 are respectively connected to a flexible structure 4;

[0059] Specifically applied to this embodiment, the connecting rod may include a first connecting rod 318 , a second connecting rod 319 , a third connecting rod 311 and a fourth connecting rod 312 .

[0060] When the motor 315 drives the screw rod 316 to rotate, the screw rod 316 drives the nut 317 forward or backward, thereby driving the second fixed block 313 connected to the nut 317 and the first fixed block 314 connected to the screw rod 316 to run towards or in the opposite direction, shortening or lengthening the flexible structure 4 connected to the first fixed block 314 and the second fixed block 313, respectively, so that one end of the layer mechanism 1 rises or falls.

[0061] like Figure 5 As shown, the first fixing block 314 and the second fixing block 313 are also connected to the slide groove 51 through the guide wheel 52, so that the first fixing block 314 connected to the nut 317 and the second fixing block 313 connected to the screw rod 316 can run in opposite directions or in opposite directions; the structure is simple, easy to use, and has high operational flexibility.

[0062] Reference Figure 8 , showing a schematic diagram of a winch adjustment mechanism 32 of the present invention, such as Figure 8 As shown, the adjusting mechanism 3 may further include a hoisting adjusting mechanism 32 .

[0063] The hoisting adjustment mechanism 32 includes a motor 322 and a reel 321; a flexible structure 4 is connected to the top and bottom of the reel 321 respectively. When the motor 322 rotates, it drives the reel 321 to rotate, shortening or lengthening the flexible structures 4 connected above and below respectively, thereby causing one end of the layer mechanism 1 to rise or fall.

[0064] It is worth noting that the roller 321 includes two annular grooves, which are used to accommodate a flexible structure respectively. The number of the annular grooves can be any number set by technicians in this field according to actual conditions. This embodiment does not limit this, such as using one annular groove to accommodate two flexible structures.

[0065] It should be noted that the above-mentioned connecting rod adjustment mechanism 31 and winch adjustment mechanism 32 are merely examples of this embodiment, and the purpose of the invention of this embodiment can also be achieved by adjustment mechanisms of other structures. This embodiment does not impose too many restrictions on the specific structure of the adjustment mechanism.

[0066] Further application of this embodiment, such as Figure 5 As shown, when there are multiple connecting rod adjustment mechanisms 31, the connecting rod adjustment mechanisms 31 are arranged on the top plate in a stacked manner.

[0067] like Figure 6 As shown, the fixing mechanism 2 also includes a top plate; when the number of the hoisting adjustment mechanisms 32 is multiple, the hoisting adjustment mechanisms 32 are arranged on the top plate in a staggered manner, and the staggered manner includes up and down staggering and front and back staggering, so as to avoid overlapping positions of the flexible structure 4, save space, and reduce the volume of the equipment.

[0068] Reference Fig. 9 , showing a schematic diagram of a chute 6 of the present invention, such as Fig. 9 As shown, the side plate 21 is provided with a slide groove 6, the guide wheel 22 is located in the slide groove 6, the slide groove 6 includes a notch 61, and the guide wheel 22 passes through the notch; the layer plate mechanism 1 includes a guide wheel 22 in the slide groove 6 connected to the side plate 21.

[0069] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
